A Proven Performer
Since its introduction in 1968, the 3175 has proved itself over and over again. Thousands of installations attest to its remarkable performance even under the severest conditions. And for ease of maintenance, it cant be beat. Customers know they can rely on the 3175 for minimum downtime, increased productivity.
Black liquor circulation pump (3175 XL) on spring-loaded baseplate.
Taking suction from a large stock tank... the 3175 is the preferred pump in the Pulp & Paper Industry
3175s on process service such as multi-effect evaporators.
Preventive maintenance is fast and easy on a 3175.

A 3175 installed in a major chemical plant.
External Impeller Adjustment Impeller clearance can be easily reset by external adjustment to maintain hydraulic performance. Delivers long time energy savings, while downtime is kept to a minimum.
Heavy Duty Shaft Designed for continuous service under most severe operating conditionsdry end broke, repulper, hydropulper, blowtank. Low deflection at maximum load for long seal and bearing life, extended MTBF.
Fully Open Impeller Special warped vane, heavy duty open type for paper stock handling. Back pump-out vanes reduce stuffing box pressure, and help prevent solids from entering sealing chamber.
Renewable Wear Parts Low maintenance costs because all wear parts...suction sideplate, impeller, stuffing box cover, shaft sleeve and throat bushing...are easily replaced.
Optional TaperBore Seal Chamber Features an enlarged bore for improved lubrication and cooling of the mechanical seal. The tapered throat keeps solids away from seal faces and from building up in the chamber. Seal life is remarkably extended.
Patented Condition Monitor Constantly measures vibration and temperature at the thrust bearing. Colored LEDs indicate general pump health. Provides early warning of improper operation before catastrophic failure occurs.
Standard Labyrinth Oil Seals Prevent contamination of lubricant for extended bearing life.

Maximum Sealing Flexibility
Dynamic Seal For elimination of mechanical seal problems; reduced maintenance Goulds Dynamic Seal pumps are designed to handle the tough applications where conventional mechanical seals or packing require outside flush and constant, costly attention. The major advantage is that external seal water is not required, thus eliminating leakage, pumpage contamination, product dilution and problems associated with piping from a remote source.
TaperBore Seal Chamber Goulds optional TaperBore seal chamber features an enlarged bore for improved lubrication and cooling of the mechanical seal. The design features a tapered throat and a vane particle ejector to keep solids away from seal faces and from building up in the seal chamber. Seal life is remarkably extended.
Standard Model 3175 pumps can be fitted with a repeller between the stuffing box and impeller. At startup, the repeller functions like an impeller and pumps liquid from the stuffing box. When the pump is shut down, a conventional static seal prevents pumpage from leaking.
The 3175 is easily field converted to Dynamic Seal. Goulds retrofit kit includes repeller, stuffing box cover, repeller plate, shaft sleeve and choice of static sealing arrangement.
